1.5 carat round lab-grown engagement ring price

How much is a 1.5 carat round lab-grown engagement ring?

Short answer: at Lavora Diamonds, a 1.5 carat round lab-grown solitaire (F color, VS1 clarity) in 14K yellow gold lands at the $2,000 complete-ring minimum on our ring price estimator. That covers the IGI-certified center, the setting and your custom 3D render.

By Lavora Diamonds, Provo, Utah. Updated October 2026.

A 2.0ct F/VS1 solitaire in 14K white gold also models at the $2,000 Lavora minimum, so a 1.5 carat round in the same grade lands there in white or yellow gold. A $2,000 budget at 1.5 carats leaves room to upgrade the color grade, add a hidden halo or size up the stone. A 2 carat E–F/VVS2 round solitaire in 14K yellow gold is $2,175–$2,425. Your exact price comes with your 3D render. Complete engagement rings have a $2,000 minimum.

How big is a 1.5 carat round?

A round brilliant spreads its weight evenly in a circle and has the most sparkle of any shape. Measurements below come from IGI-graded lab-grown stones in our supplier feed, October 2026.

Center	Face-up size
1ct round	about 6.4–6.6 mm across
1.5ct round	about 7.3–7.5 mm across
2ct round	about 8.1–8.2 mm across

Going from 1.5 to 2 carats adds about 0.7 mm of diameter on a round. Compare millimeters, not just carats, and check the size on your 3D render.

Buying tips

• Cut grade: IGI reports give round brilliants an overall cut grade. Ask for the cut grade on the exact stone, because it drives sparkle more than any other grade.
• Clarity: VS1+. Round brilliant faceting hides small inclusions well, and VS1 is our floor.
• Just under 1.5: demand clusters at round numbers, so a 1.40ct with the same grades can cost less than a 1.50ct with no visible difference on the hand. Ask us to price both.
• Other sizes: see 1 carat round prices and 2 carat round prices.
